Taste changed
Start with grind, dose, yield, coffee and temperature before assuming maintenance is the cause.
Espresso troubleshooting
Start with the symptom — not the cleaning product.
Espresso problems can come from the recipe, puck preparation, coffee, machine settings, maintenance or a genuine hardware fault. Choose the symptom that best matches what changed.
Quick diagnosis
What changed first?
That first symptom usually tells you whether to start with the recipe, the brew path, the water system or the machine itself.
Shot speed changed
Compare flow with and without coffee to separate puck resistance from a machine-side restriction.
Steam or temperature changed
Check steam-tip blockage, warm-up, settings and wider water-system symptoms.
Leak, noise or warning
Use the exact symptom page. These problems should not automatically be treated with descaler or cleaning tablets.
Taste & extraction
When the espresso itself is the problem.
Espresso tastes bitter
Check extraction, coffee and brew-path cleanliness in the right order.
Diagnose bitter espresso →
Espresso tastes sour
Separate pleasant acidity from under-extraction and recipe imbalance.
Diagnose sour espresso →
Espresso tastes weak
Check dose, yield, grind, channeling and coffee before blaming the machine.
Diagnose weak espresso →
Espresso pouring too fast
Usually a brew-resistance problem: grind, dose, basket or puck preparation.
Diagnose fast flow →
Espresso pouring too slowly
First determine whether the restriction is in the puck or the machine.
Diagnose slow flow →Machine performance
When something about the machine has changed.
Low steam pressure
Start with the steam tip, warm-up and milk-system design before considering scale.
Diagnose steam pressure →
Coffee not hot enough
Check cup heat loss, warm-up, temperature settings and broader water-system symptoms.
Diagnose temperature →
Excessive noise
Separate pump buzz, vibration, grinder noise and genuinely mechanical sounds.
Diagnose unusual noise →Warnings & leaks
When the machine is telling you something — or losing water.
Maintenance or recipe?
Not every espresso problem needs a maintenance product.
Start with the recipe when…
The problem is mainly taste, strength or shot speed and the machine’s water flow, steam and temperature otherwise seem normal.
Maintenance becomes more relevant when…
There is a broader change in water flow, steam, temperature, a compatible cleaning warning, or the machine is due for a known maintenance task.
